MILK-VAT.

SPECIFICATION forming part of Letters Patent No. 757,569, dated April 19, 1904i.

. is a specification.

My invention relates to improvements in sheet-metal vats for heating milk in the proc-v ess of making cheese; and it pertains more especially, first, to the construction of the seams, by which they perform thev twofold function ofholding the separate sheets of metal together and as strengthening-flanges to prevent the bottom of the vat from bend- .Y

ing or buckling by pressure or weight; VWsecond, to the construction of the vat at the converging ends of the seams of the bottom whereby the same is permitted to yield slightly without breaking; third, to the con-` struction and arrangement of the strengthening-anges and stay-bars upon the sides of the seams, which cooperate with the seams to stiffen the walls of the vat; fourth, to the construction and arrangement of the vertical sides of the vat; fifth, to the construction and arrangement of the strengthening-bands and bridge-blocks, which bridge-blocks are located at the junction of said bands with the longitudinal seams, and, sixth, to the manner of supporting the intermediate strengtheningbars between the sides of the bottom and the central longitudinal seam of the vat.

The construction of my invention is further explained by reference to the accompanying drawings, in which Figure l represents a side view. Fig. 2 is a longitudinal section. Fig. 3 is a bottom view. Fig. 4: is a transverse section drawn on line a: of Fig. l. Fig. 5 is a detail in section drawn on line x of Fig. 3, and Fig. 6 is a detail drawn on lineg/ y of Fig. 3.

Lilie parts are identied by the same reference-letters throughout the several views.

My invention comprises two vats-an exterior vat A for the reception of hot water, which may be heated by steam-coils or in any other convenient manner, and the interior vat B for the reception of the milk. rIhe interior vat Bis suspended from the upper edges of the vat A by horizontal flanges C. The respective vats are composed of a plurality of sections or separate sheets of metal D, which are connected together by longit/udinal seams E and transverse seams F. The seams E and F are formed by bending the contiguous edges of the several sections at right angles to their surfaces, forming downwardly projecting flanges G G, which are soldered or otherwise secured together, and owing to the depth or width of said bends they serve to strengthen the walls of the vats and prevent them from buckling or bending, as they would otherwise doif seamed together in the ordinary manner.

VIt will be understood that when the milk has been withdrawn from the inner vat B and the Same is surrounded by water in the vat A the buoyancy of the water in the exterior vat (which is equal to its weight) is such as to press upwardly against the bottom of the interior vat with great force, whereby it becomes necessary to provide the vat, with rigid strengthen: ing flanges or seams to prevent the same from being sprung inwardly when relieved of. its contents, while the pressure and weight of the water within the exterior vat has a tendency to spring the bottom of the same outwardly and downwardly, and it also becomes equally important to'strengthen said exterior vat to resist the outward and downward pressure from within. In View of the excessive pressure to which the vat is subjected I have provided the several seams at the junction of the sections with additional strengthening bars or iianges H, which are bolted or otherwise secured to the respective sides of the iianges or angular bends G G, as indicated in Fig. 6. As the exterior vat A is not subjected to moisture, I preferably form the strengthening bars or flanges H of wood and secure them to the iianges Gr by bolts I I and angular plates J J, as indicated in Fig. 6. As the wooden bars would be objectionable on the inner vat B, which is submerged in water, I preferably employ fiat bars of metal K K upon the respective sides of the flanges or seams G G, as'indicated in Fig. 3. In addition to the seams and downwardly-projecting anges located at the junction of the sections of metal comprising the bottom and sides of the vat I preferably employ one or more transverse reinforcing-bands L L, which are secured at their respective upper ends to the side rails M M of the eX- terior vat, while their central portion extends downwardly and beneath the bottom of the vat, as indicated in Fig. 3. The bands L L are preferably made of angle-iron to give them additional strength, and they are reinforced at their centers by bridge-blocks O and angleirons P P, the bridge-blocks O and angle-'irons P P being secured thereto by bolts Q Q,- as shown in Fig. 5. Heretofore it has been common to join the converging ends of the seams and strengthening-flanges at the center of the bottom of the inner vat, owing to which construction experience has demonstrated that such strengthening-flanges were liable to be broken at such point by the upward external pressure of the water in the exterior vat. I have demonstrated by experience that the strength and durability of the vat is increased by removing a portion of the converging ends of the seams and strengthening-anges Eand F of the center of. the vat, as indicated at R, when I reinforce the center of the bottom at such point by the disk or metal plate S,which is secured to the bottom of the vat by a plurality of rivets T. The bottom of the respective vats are preferably made V-shaped in cross-section, converging downwardly from their sides to their centers, as shown in Fig. 4, and the exterior vat is provided with supporting-legs V and transverse supporting blocks or bearings U. rIhe blocks or transverse bearings U are secured to the legs by bolts or rods W.

A represents a reinforcing-bar which is l'ocated between the longitudinal seam and the sides of the bottom and is held in place by and beneath the transverse strengthening-bands L L and serves to support the bottom of the vat. B is a rectangular frame, preferably formed of wood, which is secured to the upper edge of the vat and serves to retain the same in its proper rectangular shape.

I am aware that the longitudinal contiguous edges of cylindrical vessels-such as tubing, oil-tanks, te-have heretofore been bent outwardly at right angles to the cylindrical portions of the vessel and secured together by boltsl for the purpose of forming the joints between such longitudinal edges; but such angular ianges have not, so far as I have knowledge, heretofore been used for strengthening-flanges for open-mouthed vessels, mill;- vats, &c.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. An open-mouthed vessel such as a milkvat comprising a plurality of sections of sheet metal having their contiguous edges bent outwardlyl at right angles to their central portions and secured together soas to perform the twofold function of seams and strengthening-flanges in combination with parallel reinforcing-bars rigidly affixed to, and in direct contact with the sides of said strengtheningflanges,- substantially as set forth.

e Q. A milk-vat comprising a plurality of sections of sheet metal, having their contiguous edges bent outwardly at right angles to their central portions and secured together, forming seamsv and strengthening-iianges in combination with one or more transversely-arranged reinforcing bands located between their respective ends and the center of the vat, secured at their respective upper ends to the side rails of the vat, and having their central portions extending downwardly and beneath the bottom of the vat, substantially as set forth.

3. A milk-vat comprising a plurality of sections of sheet metal, having their contiguous edges bent outwardly at right angles to their central portions and secured together, forming seams and strengthening-flanges in combination with one or more transversely-arranged reinforcing bands located between their respective ends and the center of the vat,

and reinforcing bridge-blocks O, and angleirons P, P secured to the center of said reinforcing-bands at their junction with the longitudinal seams or 'strengthening-flanges of the sheet-metal section comprising the bottom of the vat, substantially as set forth.

4. A milk-vat comprising a plurality of sections of sheet metal, the contiguous edges of which are secured together by right-angular bends adapted to serve the twofold functions of seams and strengthening-flanges in combination with longitudinal reinforcing-rails H and angle-irons J, J, secured to the longitudinal central iange of the vat by a plurality of bolts, substantially as set forth. l

5. A milk-vat comprising a plurality of separate sectionsof sheet metal, secured together at their contiguous edges by right-angular bends forming seams and strengtheninganges which seams and strengthening-flanges are arranged both longitudinally and transversely of the vat 'and converge toward the center of the bottom, from the ends and sides of the vat, terminating at slight distances apartl in combination with a separate plate o f metal centrally located beneath the converging ends of said strengthening-anges and secured to the bottom of the vat by a plurality of rivets, substantially as, and for the purpose specified.

6. A milk-vat comprising a plurality of sections of sheet metal, having their contiguous edges bent outwardly at right angles to their central portions and secured together so as to perform the twofold functions of seams and IOO IIO

In testimony whereof I ax my signature in .the presence of two Witnesses.
